    The volume of a cube is: V = s^3

    you are wrong.. :) v = s^3 144 = s^3 s = cbrt(144) V_pyramid = (area of base)(height)*(1/3)

    volume of pyramid = 1/3*breadth*breadth*height breadth and height are same in this case and is equal to--- since side cube = 144 x^3=144 x=5.24

    volume = 0.333*5.24*5.24*52.4 since it's a cube so breadth= height

    no, i found side of cube by this formula \[(side)^3=144----side=\sqrt[3]{144}\]

    and volume of pyramid here, \[V=\frac{ 1 }{ 3 }*side*side*height\] and side=height (given) and 1/3=0.3333
